CHECK-VALVE.

Specification of Letters Patent.

Patented Aug. 30, 1910.

Application filed April 29, 1909. Serial No. 492,920.

To all whom it may concern:

Be it known that I, ENooH I-I. Hnniro, a citizen of the United States,residing at Shelby, in the county of Shelby and State of Iowa, haveinvented certain new and useful Improvements in, Check-Valves; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to new and useful improvements in check valves andmy object is to provide a valve of this kind of which the wearing partsmay be removed when so desired and a further object is to provide meanswhereby the parts may be quickly removed without disconnecting thevalves from their respective pipes.

Other objects and advantages will be hereinafter referred to and moreparticularly pointed out in the claims.

In the accompanying drawings forming part of this application, Figure 1is a central sectional view through the valve, and, Fig. 2 is atransverse sectional view thereof as seen on line 22, Fig. 1.

Referring to the drawings in which similar reference numerals designatecorresponding parts throughout the several views, 1 indicates the bodyof the valve, which may be constructed in any suitable form, to thelower portion of which is attached an inlet 2 and at one side thereof isprovided an outlet 3, said outlet being preferably positioned adjacentthe upper portion of the body. At the juncture of the inlet 2 with thebody 1, is formed a circumferential shoulder 4;, upon which is adaptedto rest a partition 5, said partition having at its central portion aseat 6, with which is adapted to cooperate a valve 7 the edge of thevalve and the face of the seat 6 being preferably tapered, so that aclose fit will result and prevent leakage between the valve and seatwhen the valve is closed.

The valve 7 is provided with an upwardly extending stem 8, which isadapted to guide the valve and is entered through a socket 9, in whichit is adapted to slide, the socket having a head 10 at its upper end,which snugly fits the interior of the body and the socket is held inposition in the upper portion of the body and the partition 5 on theshoulder 1, by introducing a casing 11 in the body 1, the height of saidcasing being such as to properly position the head within the upper partof the body, said casing having an opening 12 therein registering withthe outlet 3.

The partition, casing and socket are securely held-in fixed relationwith the body by introducing a binding cap 13 into the upper end of thebody 1, the edge of said binding cap having threads 14 thereon adaptedto engage similar threads 15 on the interior of the upper end of thebody, the central portion of the cap having an extension 16 thereon,which is adapted to receive a wrench when the cap is to be turned intoor out of the body.

It will thus be seen that the wearing parts of the valve may be renewedwhen desired and without disconnecting the valve from the pipes enteringthe inlet and outlet and as the seat and valve are practically the onlyparts that become worn, said parts may be renewed at a minimum expense,thereby greatly reducing the cost of operating the valves as the bodyand other parts thereof may be used indefinitely.

What I claim is:

1. A device of the character described, consisting of a body having aninlet and an outlet, of a valve seat arranged within said body, saidbody having an annular shoulder in its lower part forming a support forsaid valve seat, an inner casing resting on said valve seat and snuglyengaging the inner walls of said body member, a valve resting upon saidvalve seat, a socket receiving the stem of said valve, said sockethaving an annular head resting upon said inner casing, and a cap havingscrew threaded connection with said body and engaging the head of saidsocket.

2. A device of the character described, comprising a body having ashoulder upon its inner lower end, a valve seat resting upon saidshoulder, an inner casing arranged in said body and engaging said valveseat the sides of said casing snugly engaging the inner walls of saidbody member, a valve engaging said valve seat and having an upwardlyextending stem, a socket receiving said stem and having a head engagingthe upper end of said casing and a cap engaging said body and said head,said socket having a tubular formation depending from its head to apoint a short distance from said valve.

3. In a device of the character described,

the combination With a body member having an inlet and outlet and acircumferential shoulder adjacent the bottom portion there of; of apartition resting on said shoulder and having a seat therein a socketadapted to rest in said seat and having an upstanding stem thereon aremovable casing with an opening in one side thereof adapted to registerwith said outlet, said casing resting on said partition and snuglyengaging the inner Walls of said body member, a socket having a headthereon resting on the upper edges of said casing, said socket beingtubular in shape and said stem extending therethrough, said head formingwith said socket an approximately T shaped member With an openingextending through the axial center thereof, and a threaded cap adaptedto engage the upper portion of said body member and rest firmly on theupper face of the head of said socket, whereby the parts within saidvalve may be securely held and readily removed.

In testimony whereof I have signed my name to this specification in thepresence of tWo subscribing Witnesses.
